Introduction
This User’s Guide explains how to install and use the Adaptec
AEC-4412B and AEC-7412B External RAID Controllers, which are
designed to be installed in a RAID enclosure and used with a host
system to provide a powerful disk subsystem. The canister is
designed to fit in a 5.25-inch half-height disk bay. The AEC-4412B
controller supports single-ended or differential host UltraSCSI
buses. The AEC-7412B supports Fibre Channel-to-UltraSCSI, single
loop.
The AEC-4412B RAID controller is a fault-tolerant SCSI-to-SCSI
RAID controller that bridges the SCSI interface between the host
system and the SCSI hard drive peripherals.
The AEC-4412B has one UltraSCSI input channel and two UltraSCSI
output channels. Each output channel is a separate SCSI bus.
The AEC-7412B has one fibre channel (FC) input and two UltraSCSI
output channels. Each output channel is a separate SCSI bus.
Administrative software is embedded in firmware; thus, the
AEC-4412B/7412B requires no specific software drivers for the host
operating system.

Upgrade Options
The design of the AEC-4412B and the AEC-7412B RAID controllers
includes daughter boards that can be upgraded to reconfigure the
controller. Adaptec offers the following three daughter board
options:
■Single-ended UltraSCSI
■Differential UltraSCSI
■Single Loop Fibre Channel
By exchanging the daughter board installed in your controller with
one listed above, you can reconfigure the controller to meet your
changing needs. For example, you can change your single-ended
configuration to differential UltraSCSI. Likewise, you can upgrade
to fibre channel as the need arises.

Hardware Installation
This chapter covers the hardware installation of the AEC-4412B/
7412B External RAID Controller.
AEC-4412B Canister Installation Steps
1
Prepare the host system by using a SCSI host adapter such as
the AHA-2940UW for the host connection.
2
Enable external termination for the host channel on the I/O
board (for differential SCSI only).
Note:
Termination is automatically set for single-
ended SCSI only.

Current Date: 3/19/98 ECN Date: 3/20/98
3
Insert the AEC-4412B into an available 5.25-inch half-height
disk bay and secure it in place by screwing it to the mounting
brackets.
Note:
Use a minimum of four, size 6-32 screws with a
maximum length of 3/8 of an inch.
4
Connect the host SCSI output to the SCSI CHANNEL 2/HOST
connector on the back of the canister. Use a standard host SCSI
cable.
5
Connect the external SCSI drive array(s) to the drive CHAN-
NEL 1 SCSI and/or drive CHANNEL 0 SCSI connectors on the
back of the Canister. With additional cables, up to fifteen
drives can be connected to each SCSI output channel. Use
